Today’s electronic devices use a source of technology called LED. LED emits blue light as strong as ever, making us more vulnerable to the damage.
Blue light, natural or artificial have very short wavelengths, resulting in higher amounts of energy
The blue light or (HEV) high energy visible light flickers more easily than lights with longer wavelengths. These strong flickers produces a glare that causes eye strain, headaches, and physical or mental fatigue.
Drastic exposure to the artificial blue light from electronics causes serious long term damage to eyes, since our eyes do not develop any protection from the light.
According to studies, 60% of the people in the world spend at least 6 hours in front of a digital device every day.
Harmful effects include disruption of the circadian rhythm ( physical, mental, & behavioral changes according to the time of day; body’s signal time to sleep, eat, etc.), Digital Eyestrain Syndrome, risk of certain types of cancers (iris melanoma & large choroidal melanoma), heart disease, obesity, diabetes, depression, and of course, loss of vision.
